160 results about "Chalcanthite" patented technology

Chalcanthite, whose name derives from the Greek, chalkos and anthos, meaning copper flower, is a richly colored blue/green water-soluble sulfate mineral CuSO₄·5H₂O. It is commonly found in the late-stage oxidation zones of copper deposits. Due to its ready solubility, chalcanthite is more common in arid regions.

Preparation method of quality control serum for quality control of centrifugal microfluidic chips

The invention discloses a preparation method of quality control serum for quality control of centrifugal microfluidic chips. The method comprises the following steps: adding 0.6 to 1.0 percent of cholesteryl sodium sulfate into bovine plasma, and adding 0.02 to 0.06 percent of monopotassium phosphate; sequentially adding 0.04 to 0. 08 percent of ammonium ferric sulfate dodecahydrate, 0.5 to 0.9 percent of calcium chloride, 0.2 to 0.6 percent of bitter salt, 0.6 to 1 percent of urea, 9 to 13 percent of sodium chloride, 0.01 to 0.03 percent of zinc vitriol, 0.01 to 0.03 percent of chalcanthite,0.06 to 0.2 percent of glycocholic acid, 2 to 4 percent of glucose, 0.03 to 0.06 percent of creatinine, 0.08 to 0.2 percent of uric acid, and 0.07 to 0.11 percent of triolein into water; uniformly mixing obtained solution; adding glycol, saccharose and triton X-100, and uniformly mixing; sequentially adding albumin bovine serum, sodium azide, alanine aminotransferase, aspartic transaminase, alkaline phosphatase, lipase and creatine kinase, uniformly mixing, and performing freeze drying. The method has the advantages that the source of the raw materials is sufficient, the raw materials are easyto get, possible matrix effect is furthest avoided, and precipitation of the raw materials is prevented.

Method for treating copper-containing etching waste solution

The invention discloses a method for treating a copper-containing etching waste solution. The method comprises the steps of mixing an acid etching waste solution, a first pH regulator, hydrogen peroxide and a first flocculating agent, and filtering to obtain a copper chloride solution; mixing an alkaline etching waste solution, a second pH regulator, magnesium chloride and a second flocculating agent, and filtering to obtain an ammoniacal copper solution; mixing a part of copper chloride solution, a part of ammoniacal copper solution and ammonium hydroxide, filter pressing, washing, and filterpressing to obtain a third filter cake and a first post-filtration solution; pulping the third filter cake to obtain a fourth post-mixed solution; mixing concentrated sulfuric acid and the fourth post-mixed solution, and cooling to obtain a chalcanthite crystal; filtering and dewatering the chalcanthite crystal to obtain a copper sulfate product; mixing and dewatering the other part of copper chloride solution, the other part of ammoniacal copper solution and ammonium hydroxide so as to obtain water-containing copper chloride hydroxides and a second post-filtration solution; drying the water-containing copper chloride hydroxides to obtain copper chloride hydroxides; and mixing the first post-filtration solution, the second post-filtration solution and an alkaline liquor to obtain the alkaline etching solution.

Method for producing copper sulfate from copper-bismuth scum

The invention discloses a method for producing copper sulfate from copper-bismuth scum, which comprises the steps of pretreatment, leaching, iron removal, calcium/magnesium removal, and crystallization and concentration. The method specifically comprises the following steps: crushing and grinding the raw material copper-bismuth scum, adding a sulfuric acid solution, introducing oxygen or oxygen-enriched air to react, filtering, adding oxydol into the leach solution to react, concentrating, regulating the pH value to 2-4, carrying out hydrolysis reaction to obtain a ferric hydroxide precipitate, carrying out pressure filtration to obtain a filtrate a and a filter residue b, heating the filtrate a, concentrating, cooling, and filtering to obtain a filtrate c and a filter residue d; and concentrating and crystallizing the filtrate c, and carrying out vacuum centrifugal separation to obtain the target substance. The method overcomes the defect of comprehensive recovery in the existing copper-bismuth scum treatment process. According to the method, the raw material copper-bismuth scum containing 10-40% of copper and 30-50% of bismuth is subjected to oxygen pressure leaching by the dilute sulfuric acid solution, the obtained leach solution is subjected to iron/calcium/magnesium removal, and the concentrated crystal is dried to obtain the YS/t94-2007 top-grade chalcanthite product.

Traditional Chinese medical unguent preparation for curing dermatosis and preparation method thereof

The invention relates to traditional Chinese medical unguent preparation for curing dermatosis and a preparation method thereof and belongs to the technical field of traditional Chinese medicine manufacturing. The traditional Chinese medical unguent preparation is prepared from raw materials of radix notoginseng, common bletilla tuber, Chinese angelica, rhizoma corydalis, olibanum, myrrh, peach kernel, elephant skin, radix angelicae pubescentis, fructus toosendan, radix sophorae flavescentis, rhizoma coptidis, radix scutellariae, radix et rhizoma rhei, cortex phellodendri, cortex dictamni, radix arnebiae, herba salviae Chinesnsis, radix et rhizoma rubiae, fructus gardeniae, radix gentianae, cortex pseudolaricis, impatiens balsamina flower, galla chinensis, sepiae endoconcha, radix rumicis, radix scrophulariae, semen hydnocarpi, radix ampelopsis, fructus gleditsiae, borneol, alums, borax, camphor, chalcanthite, realgar, minium, sulphur, semen armeniacae amarae, radix trichosanthis, semen pruni and yellow Vaseline cream. The raw materials are de-dusted, dried, mixed, smashed and extracted to be prepared into the traditional Chinese medical unguent preparation. The traditional Chinese medical unguent preparation is reasonable in match of raw traditional Chinese medicine, obvious in curing effect, simple in preparation technology, safe, free of toxic and side effect, low in manufacturing cost, convenient to use, concentrated in target and strong in medical applied force. In addition, the dermatosis is not prone to relapse, and the traditional Chinese medical unguent preparation can be directly applied to the nidus position instead of being dosed through digestive tracts.
